Summary
This study found mandibular fracture surface temperatures are warmer than surrounding bone. Internal bone temperatures within mandibular fractures decrease after biopsy cavity creation.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Surgical Thermography
Background:
- Understanding thermal dynamics in bone healing is crucial for surgical outcomes.
- Mandibular fractures present unique challenges due to the complex anatomy and vascularity.
- Accurate temperature measurement aids in assessing tissue viability and inflammatory responses.
Purpose of the Study:
- To measure and compare temperatures at various points in and around mandibular fractures.
- To investigate the thermal effects of biopsy cavity creation on bone temperature.
- To determine the relationship between surface and internal bone temperatures in mandibular fractures.
Main Methods:
- Utilized a calibrated thermocouple and digital thermometer for precise temperature readings.
- Measured temperatures on the bone surface margin of mandibular fractures and at distant sites.
- Recorded internal bone temperatures within fracture sites at varying depths and post-biopsy intervals.
Main Results:
- Surface temperatures at the mandibular fracture margin were approximately 1°C warmer than at 5 and 10 mm distant sites.
- Internal bone temperatures showed a reduction at 1 and 2 minutes following biopsy cavity creation.
- Confirmed that surface temperatures are lower than internal bone temperatures in the studied mandibular fractures.
Conclusions:
- Mandibular fracture sites exhibit distinct thermal profiles compared to adjacent bone.
- Surgical interventions like biopsy can transiently alter local bone temperature.
- Surface temperature measurements may not fully represent the thermal state of internal bone structures in mandibular fractures.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
